28 The bcachefs filesystem - a modern, copy on write filesystem, with
29 support for multiple devices, compression, checksumming, etc.
32 bool "bcachefs quota support"
33 depends on BCACHEFS_FS
36 config BCACHEFS_ERASURE_CODING
37 bool "bcachefs erasure coding (RAID5/6) support (EXPERIMENTAL)"
38 depends on BCACHEFS_FS
41 This enables the "erasure_code" filesysystem and inode option, which
42 organizes data into reed-solomon stripes instead of ordinary
45 WARNING: this feature is still undergoing on disk format changes, and
46 should only be enabled for testing purposes.
48 config BCACHEFS_POSIX_ACL
49 bool "bcachefs POSIX ACL support"
50 depends on BCACHEFS_FS
54 bool "bcachefs debugging"
55 depends on BCACHEFS_FS
57 Enables many extra debugging checks and assertions.
59 The resulting code will be significantly slower than normal; you
60 probably shouldn't select this option unless you're a developer.
63 bool "bcachefs unit and performance tests"
64 depends on BCACHEFS_FS
66 Include some unit and performance tests for the core btree code
68 config BCACHEFS_LOCK_TIME_STATS
69 bool "bcachefs lock time statistics"
70 depends on BCACHEFS_FS
72 Expose statistics for how long we held a lock in debugfs
74 config BCACHEFS_NO_LATENCY_ACCT
75 bool "disable latency accounting and time stats"
76 depends on BCACHEFS_FS
78 This disables device latency tracking and time stats, only for performance testing
80 config BCACHEFS_SIX_OPTIMISTIC_SPIN
81 bool "Optimistic spinning for six locks"
82 depends on BCACHEFS_FS
86 Instead of immediately sleeping when attempting to take a six lock that
87 is held by another thread, spin for a short while, as long as the
88 thread owning the lock is running.
90 config MEAN_AND_VARIANCE_UNIT_TEST
91 tristate "mean_and_variance unit tests" if !KUNIT_ALL_TESTS
93 depends on BCACHEFS_FS
94 default KUNIT_ALL_TESTS
96 This option enables the kunit tests for mean_and_variance module.
